If there is no record of nucleic acid detection within 7 days in Shanghai, the "application code" will be given a yellow code. What is the purpose of strengthening nuclear testing?

Shanghai will turn the health codes of all residents who have no records of nucleic acid testing within 7 days into yellow. The reasons for strengthening nucleic acid detection behavior are mainly due to the following considerations:

The epidemic situation in Shanghai has not completely disappeared, and it is still necessary to do a good job in nucleic acid testing. After two to three months of fighting the epidemic, Shanghai has fully recovered, all posts and schools have resumed work, and residents can shop in public shopping malls with personal health codes and nucleic acid test records. From the original nucleic acid test once every two days to at least once a week now, otherwise you will face the dilemma of not going. This is to reduce the uncertain risk of the epidemic. Although there is no large-scale full-scale nucleic acid detection, people can carry out nucleic acid at the wrong peak, and the efficiency of screening nucleic acid confirmation personnel is as high as 90%.

Strengthening nucleic acid detection is to prevent the epidemic from rebounding. According to China's experience in fighting the epidemic, in a certain area, the epidemic prevention and control policy was relaxed just after the epidemic was controlled, and soon there were signs of the epidemic rebounding. In order to learn this lesson, the staff in Shanghai said that in order to prevent the epidemic from rising to the maximum extent, it is necessary to conduct nucleic acid testing within 7 days. After continuous 14 days, the one-week nucleic acid test is cancelled, and residents can decide whether to do nucleic acid test according to their own needs.

Ordinary residents do nucleic acid testing once a week, and key personnel need to do nucleic acid testing once every two days. Personnel engaged in the import and export of cold-chain food in Shanghai, as well as teachers and staff working in public places of schools, must have a nucleic acid test every two days, because these places belong to gathering places and places with high incidence of epidemic, and even after the outbreak, they can quickly take isolation measures to ensure the personal safety and travel safety of residents in most areas.

In addition to Shanghai, China's Capital Region, Zhejiang Province and Jiangxi Province, residents will be arranged to undergo full-time nucleic acid testing for one week.
